  A secondary lithium battery operates similarly to other primary batteries, providing power to devices (a process known as discharging). However, unlike primary batteries, it can be recharged and reused. For a detailed comparison between SLA (sealed lead acid) and lithium batteries, you can refer to our guide here. In this blog, we will explore  lithium battery cells  in more depth, discussing their configurations, practical applications, and how their construction makes them well-suited for specific use cases.   LITHIUM CELL FORM FACTOR When you take off the top of a lithium battery pack, you’ll first notice the individual cells and a circuit board of some kind. There are three types of cells that are used in lithium batteries: cylindrical, prismatic, and pouch cells. For the purpose of this blog, all cells are lithium iron phosphate (LiFePO4) and 3.2 volts (V).   CYLINDRICAL LITHIUM CELLS   A  cylindrical cell  resembles a traditional household battery, like a AA battery, which insp

  Cylindrical batteries   can be categorized based on their filler materials into several types: lithium iron phosphate batteries, lithium cobalt oxide batteries, lithium manganese oxide batteries, and cobalt-manganese hybrid batteries. Additionally,  cylindrical lithium batteries  are differentiated by their shell types, which include steel shell lithium batteries and polymer shell lithium batteries.   Part 1: Characteristics of Cylindrical Batteries 1. Appearance of Cylindrical Lithium Batteries Cylindrical lithium batteries typically consist of a positive electrode material (such as nickel-cobalt oxide or zinc-manganese oxide), separator paper, and an electrolyte. The battery casing is usually made from an aluminum-plastic composite pipe.   2. Capacity of Cylindrical Lithium Batteries The rated energy density of a single cylindrical lithium battery ranges from 300 to 500 Wh/kg, with a specific power exceeding 100 W. The actual performance can vary depending on the model and specific

 In the realm of  lithium-ion batteries , the 26650 and 18650 models have gained significant popularity. While they share some common features, their differences are key to understanding their unique advantages. This article explores the distinctions between these two battery types in detail.   Before delving into their specific characteristics, it's essential to grasp the basics of lithium-ion batteries. The names 26650 and 18650 are derived from their physical dimensions:   -  26650 Battery ​: 26mm in diameter and 65mm in length - 18650 Battery: 18mm in diameter and 65mm in length   Though these size differences may seem minor, they significantly influence each battery's performance and utility.   26650 Battery: An Overview   The  26650 lithium-ion battery , being larger than the 18650 model, offers a higher energy capacity. This increased size enables it to achieve a greater ampere-hour (Ah) rating, reflecting its ability to store more energy.   Thanks to its superior capaci

  A 26700 battery, or a 26700 cell, typically refers to a cylindrical rechargeable battery. The name "26700" might sound like a code from a sci-fi movie, but it actually refers to a specific battery size. The "26" denotes the diameter of the battery in millimeters, while "700" signifies its length, also in millimeters. For reference, this battery is slightly larger than the more commonly known 18650 and 21700 battery sizes. 26700 lithium-ion batteries  are high energy density batteries with a long cycle life and no memory effect. They are suitable for EV battery packs and solar farms. When buying a 26700 lithium-ion battery, you can consider things like voltage and capacity, charge/discharge rate, depth of discharge, life span, warranty, and expandable capabilities.   Key Features of the 26700 Lithium-ion Battery Capacity and Energy Density   One of the standout features of the 26700 battery is its high capacity. Typically, these batteries have a capacity

  Xiaolu Battery   was established in Jining Economic Development Zone in July 2019, with a registered capital of 253 million Chinese Yuan and more than 500 employees. It is a new energy technology enterprise specializing in the research and development, production, sales and application of lithium-ion batteries . The company has the domestic first-class lithium automatic production line, in order to meet the diversified needs of customers, the company designed and developed battery cell and battery module products, covering power, power tools, digital appliances, energy storage and other fields, with high safety and reliability, high energy density, long cycle life, cost-effective and other multiple advantages, since the production of products in short supply. In 2021, the first production line of the enterprise will be put into full operation in the first year, achieving an output value of 150 million Chinese Yuan. By 2022, the output value will reach 300 million Chinese Yuan.
